Summarize by each event to show the Collision Probability for each fragment size at the last recorded time, if that time is within a day of TCA.
Summarize by each event to show the Collision Probability for each fragment size at the last recorded time, for each binned days to TCA.
We need to find a range of values to appropriately label events of concern.
How many events have \(\text{Collision Probability} = 0\) when \(\text{days to TCA} < 1\)?

as a surrogate to label a concern event.
How is our visibility of concern events limited?
How many Concern Events if the threshold is \(1\text{e-}5\)?
We focus our initial analysis on concern events with fragment size of \(>= 1\) fragment. Future methodology will include events with higher fragment sizes.
